摘要： Even if high speed are available between the router and the multimedia unit through the IP line (up to 24 Mbits/sec), this is still the bottleneck in term of data transfer. Indeed in practice the vast majority of IP users have access speed between 2 to 5 Mbits/sec and the development of other services (telephony, videoconference, push VOD, game) are bandwidth consuming. It is now an object of the invention to propose a solution to reduce the data flow between the router and the multimedia unit over IP line.This is achieved by a method to optimize the data stream between a router and a multimedia unit, the router receiving at least one data stream forming a service and comprising several sub-streams from which part of them are alternatively used by the multimedia unit, the method comprising the steps of: defining a set of data representing the multimedia unit's profile, transmitting this set of data to the router, filtering by the router the unnecessary sub-stream according the given profile, sending the remaining sub-streams to the multimedia unit.

摘要： A method for monitoring execution of a sequence of data processing program instructions in a security module associated to a multimedia unit connected to a managing center supplying control messages authorizing access to broadcast data streams. The security module comprises a processor for executing the instructions, a memory, and a monitoring module for analyzing the instructions before execution by the processor. The managing center comprises a security module emulator generating reference data sets by executing a sequence of instructions induced by data of a given control message in the program. The reference data sets are appended to control messages sent to the security module. The monitoring module analyzes a sequence of program instructions for determining a check data set which is compared with a reference data set received from the control messages. When the reference and check data sets match, the program continues executing. Otherwise, further control message processing stops.

摘要： The present invention provides a method for secure communication of digital information between a transmission entity and at least one reception entity. The method may be applied in the domain of audio/video data transmission, where stuffing data packets comprising random payloads are inserted into a transport stream along with true data packets comprising the audio/video data. The dummy data packets are detectable by an authorized reception entity but not detectable by unauthorized reception entities. A large number of stuffing data packets are included in the transmission to occupy bandwidth and to further render the job difficult for an unauthorized reception entity which tries to intercept the transmission.

摘要： The present invention provides a method for decrypting encrypted content transmitted from an operator to a plurality of users where said operator further provides security information allowing for the decryption of said content. The method has the advantage of satisfying the goal of providing the capability for detecting a fraudulent user who retransmits control words extracted from the security information to other users. The method provides for the achievement of the goal without incurring extra overhead in addition to the transmitted content and security information. The method makes use of control words which are based on multiple solutions provided by collisions in mathematical functions and involves the observation of choices of control words retransmitted by the fraudulent user.

摘要： As television programs increases, it becomes necessary to find means for rapidly accessing the users' preferred programs. Furthermore, television programs are addressed to different types of users such as children and adults. The proposed system processes a program grid comprising at a higher level the whole information on programs and at a lower level, information specific to a users group as well as parameters defining a user profile. The parameters are divided into several sets of parameters, each set corresponding to a filter layer allowing selecting a category or categories of required information. The first layer, defining a global restrictive filter, is defined by an administrator of the system and the following layers, defining a filter specific to a users group and containing filtering short commands, are defined by at least one member of the users group.
